In order to Fig. 1. secure a slight yieldingaction between the jaw I4 Fig. 3 is a transverse sectional view througha and shoulder s this jaw is yieldingly supported in 50 portion of themachine of Fig. 1 showing the time spaced relation to the table top bythe blade shaft. 7 springs H which may be clamped to the jaw and Fig. 4on an enlarged scale is an end view of table top by the bolts shown. theheel supporting mechanism of. the machine The slope or curvature of therear surface of of Fig. 1. heels may vary with variations in the stylesof 55 the heels. Means is therefore provided whereby the jaw l5 may beadjusted angularly to cause its heel engaging surface to conform to theinclination of the inverted heel H and to this end in the constructionshown the jaw I5 is provided with the laterally projecting ears |8 whichare pivotally secured by the clamping bolts I9 to a slide or plate 20mounted upon the table top I2 for adjustment transversely of the tabletowards and from the jaw 14 to firmly grip the-heels between these jaws.The jaw supporting plate 2|] may be secured to the table top by thebolts 2| extending through elongated slots 22 in the plate 20 and afterthe proper adjustment has been secured these bOlts may be tightened tofirmly secure the plate 28 in place. The transverse movement of theplate 20 is preferably guided by the key 23 secured to'the table top.Adjustment of the plate 2|] towards and from the .heel gripping positionmay be secured by operating the adjusting screw 24 :Which is journaledin a bracket '25 secured to the table :top and this screw has threadedengagement .with the plate '20. The adjusting screw :may be rotated bymeans of the hand knob 26. As will be :apparent in Fig. 5 the jaw F4 ispreferably somewhat longer than the jaw l5 to facilitate the placing ofthe heels flat the entrance between the jaws so that when the poweroperated plunger, to be described, moves forward "it will slide the heelalong the table top between the substantially parallel jaws. Theentrance end of the jaw |5 may be rounded slightly it-desired but thisis not essential since the curvature of the heel will serve to guide thehee'l into the space between the jaws.

In the construction shown the heel when placed upon the table top l2 inan inverted position is forced lengthwise of the relatively long jaws bythe reciprocating plunger 21 which is slidably supported by the bearingblocks 28 secured to the table top. The forward end of this plunger ispreferably provided with a socket, as will be apparent from Fig. 2,adapted to adj-ustably receive the shank of the heel engaging member 29.The arrangement is such that this heel engaging -member may be adjustedlongitudinally of the plunger slightly and clamped in the desiredposition of adjustment by tightening the set bolt 30 threaded in aprojection upon the forward end of the plunger. This adjustment of theheel engaging member '29 is provided to vary the distance the heel willbe moved lengthwise .of the jaws by the forward movement of the plunger21.

In the construction shown forward movement is imparted to the plunger2;! by a rocking lever 3|, the lower end of which is pivotally supportedwithin the machine casing at 3'2 and the upper end of this fleverextends through a slot formed in the plunger 21 .as indicated at 33.Forward movement is imparted to the lever 3| by a cam 34 keyed orotherwise rigidly secured to a transverse shaft 35 which willhereinafterbe referred toias the time shaft. This shaft, as will be apparent fromFig. 3, is journaled in bosses 36 proyided upon the side walls ll] of.the Supporting frame. The shaft may be held from moving longitudinallyin its bearing by .the driving sprocket 31 secured at-one end of thisshaft and by .a collar 38 secured to the other end of this shaft. Thecam 34 engages ;a roller 39 pivotally secured to the lever 13:! :andforces this lever forward to impart a working stroke to the plunger 21.This lever in the construction shown is retracted to return the plungerto the dotted line position of Fig. 2 by the spring 40 one end of whichmay be connected to the lever 3| and the other to the machine frame.

The time shaft 35 which is shown as disposed near the forward end of themachine is driven, in the construction shown, from a transverse shaft 4|disposed near the discharge end of the machine, and which willhereinafter be referred to as the clutch shaft. This clutch shaft hasloosely journaled thereupon at the rear of the frame H], a drivingsprocket 42 which is driven from a motor 43 by the chain 44.(Jo-operating withthe sprocket 42 is a clutch or disk 45 which is,connected to the shaft 4| for sliding movement thereupon into and outof friction engagement with the outer face of the sprocket 42 and thesliding movement of this clutch element 45 into and out of frictionengagement with the sprocket 42 is controlled .by the lever 45, theupper end :of which is :pivotally secured to a supporting bracket 41secured "to the .casing and :the lower end .of this lever is operativelyconnected to :the :upwardly extending portion 48 of a foot treadle .49.Anintermediate portion of the lever 46 has "the enlarged hub 50 which is.operatively connected to the clutch member 45. The treadle .ispivotally supported at 5| upon a bracket 52 secured to the machinecasing and the upwardly extending portion '48 of the foot treadle has anelongated slot adapted to receive a pin 53 secured to the 'lower portionof the clutch operating lever 46. The clutch is normally held in itsinactive .position by a spring '54 and is held in friction engagementwith the sprocket 42 to drive the shaft 4| :by depressing the foottreadle '49.

The time shaft 35 is driven from the clutch shaft 4| at .a reduced speedby providing a small sprocket 56 upon the shaft 4| adapted to drive alarge sprocket 31 upon the shaft 35 by means of :a sprocket chain 51 tothereby .turn theplunger operating cam 34 .in the direction indicated bythe arrow in Fig, 2.

The mechanism so far described serves to operate the plunger 21 toforcea heel .H along the table top from the position indicated by I inwhich it has :been :placed by hand at the entrance to the jaws l4 and I5to a position indicated by II near the discharge 'endlof these jaws, asshown in Fig. 5. This will serve :to accurately position the heel H inthe position II to be drilled and stamped :as will be hereinafterdescribed. Whereupon the heel will be moved forwardly between the jawsby the next incoming heel to the position indicated by III, as shown inFig. 5, in which position a heel strengthening dowel (1 may be driveninto the drill hole formed in the heel while this heel was in theprevious position indicated by II.

It is desirable to stamp heels during their process of manufacture withnumbers or other marks indicating size and style and this isaccomplished in accordance with the present invention by providing meansfor stamping the top surface of the inverted heel while it is in theposition II of Fig. 5. To accomplish this in the construction shown theheel stamping dies 58 are positioned below the table top to passupwardly through a hole 59 in the top of the table to engage the surfaceof the heel to be stamped. These dies are secured to an operating lever60, one end of which is pivotally supported at El upon lugs or the like62 extending downwardly from the table top I2 within the machine frame.Operating movement is im parted tothis leverIiIl by the cam 63 whichengages a roller 64 rotatably mounted at the under side of the leverbetween the spaced ears 65 adapted to straddle the peripheral portion ofthe cam 63. The lever 66 normally rests in its lower or inactiveposition in which it is shown in Fig. 7 and is periodically raised bythe cam 63 to stamp the heel H.

It is important to apply ink to the stamping dies 58 and this isaccomplished in the construction shown by providing the inking roll 66which is normally supported by the bracket 61 in the inactive positionin which this roll is shown in Fig. '7. The inking roll 66 is caused toperiodically wipe across the upper ends of the dies 58 by mounting thisroll between the horizontally extending links 68 which are pivotallysecured at 69 to the upstanding operating levers III, the lower ends ofwhich levers are pivotally secured at 1| to a transverse brace II.Rocking movement is periodically imparted to the levers 10 from thelever 3| by the connecting link 12, and a spring 13 serves to force theinking roll 66 downwardly so that it will yieldingly wipe across theupper endsof the stamping dies.

As the heel H is advanced by the plunger 21 from the position inwhich itis indicated by I in Fig. 5 towards the position indicated by II it isacted upon by a rotating circular saw 14 which cuts off the end ofthe'heel to shape this end to receive the usual top lift. -The saw 14 inthe construction shown is driven by .the motor 15 which is supported formovement in a substantially vertical direction towards and from thetable top and also for angular adjustment, to thereby vary the height ofthe shoe heel and the angle at which the surface shall be cut to receivethe top lift. The motor 15 is supported, in the construction shown, forthe adjustments just mentioned by an angle plate 16 to the uprightportion of which is pivotally mounted at 11 the angularly adjustableplate 18, and this plate is clamped in the desired position of angularadjustment by tightening the angle clamp 19.

The motor 15 is provided with a supporting head mounted upon-theangularly adjusted plate 18 for sliding movement and adapted to beadjusted towards and from the work by rotating the crank handle 8| toturn the motor adjusting screw 82. The circular saw 11 is shown ashaving the usual guards 83.

As soon as aheel H has been advanced by the plunger 21 to the positionindicated by II in Fig. 5 it may be acted upon by the twist drill 84which may be supported and operated by the drilling mechanism 85supported upon the angle plate I3. This drill press has the drivingmotor 86 which by means of the belt 81 drives a drill operating spindlewhich is rotatably mounted in the hollow shaft 88 which is non-rotatablybut slidably supported by the frame of the drill press. The entiredrillpress is mounted upon the angle plate I3 at an inclination to thevertical to accommodate the angle at which the heel is to be drilled andthe drill 84 isnormally held in its raised position by the spring 89.This drill is periodically lowered to drill the heel, in theconstruction shown, by providing upon the clutch shaft 4| the drilllowering cam 90 which is adapted to depress the lever 9|, one end ofwhich is pivotally supported from the machine frame at 92. To theopposite end of this lever 9| is pivotally connected the link 93, theupper end of which is connected by the bolt 94 to a plate or casting 95rigidly secured to the non-rotating drill shaft 88; The connecting link93 is preferably constructed with overlapping parts which may be clampedin different positions of adjustment by the bolt 96, as best shown inFig. 2, to vary the overall length of this link and thereby vary thedegree to which the drill 84 will be forced downwardly by the operatingmechanism just described.

The cams 63 and 90 are not secured to the clutch shaft 4| in the presentconstruction but are rigidly secured to a sleeve 91 journaled upon theshaft 4| and this shaft is driven from the time shaft 35 by the chain 98which passes around a sprocket 99 upon the time shaft and the sprocketI00 upon the sleeve 91 to drive this sleeve and the cams securedthereto.

In accordance with the present invention means is provided whereby whenthe drill 84 is lowered to drill a heel H in the position indicated byII a dowel driver will be operated at this time to drive a dowel d in aheel occupying a position indicated by III at this time. This isaccomplished by constructing the casting 95 so that it will adjustablysupport the dowel driving pin IOI positioned to align with a hole in aheel occupying the position indicated by III. In order to secure theproper lateral and longitudinal position of the dowel driving pin IIlIthe casting 95 is preferably formed as shown in Fig. l0 so that the pinIOI may be rigidly clamped by the bolt I02 in the pin supporting blockI03 and this block may be adjusted towards and from the axis of thedrill spindle and laterally by adjusting the different bolts I94. Thesevarious adjustments will serve to accommodate the distance which mayexist between the two heels shown in Fig. 5 when one is being drilledand the dowel is being driven into the other.

In the construction shown the dowels to be driven in the heels aresupplied from a hopper I05, which hopper may be supported above theframe of the machine by the upright I96. The dowels are fed from thishopper through the tube I01 which leads from the hopper to the dowelfeeding device I08 which is supported by a bracket I99, as best shown inFig. 6, directly above the heel in which the dowel is to be driven.

It is important that the dowels be supplied to the tube I01, one at atime in a continuous series. and this is secured in the constructionshown by providing in the hopper I05 the dowel feeding trough III]. Theupper end of this trough, as best shown in Fig. 12, is large enough toreceive a stack of several dowels but as they slide down this trough theV-shaped groove thereof decreases in height as indicated by III to asize in which it will retain only one dowel and the other dowels willslide down the inclined walls II2 to be returned to the lower portion ofthe hopper. The single row of dowels that remain in the trough III aredirected into the feed tube I91.

The dowels are delivered one at a'time into the dowel feeding device I08directly in front of the forward end I I3 of the plunger II 4 which isslidably mounted in the hollow casing of the dowel feeding device I08.This sliding plunger H4 is periodically operated to advance a "dowelfrom a position directly below the feed tube I81, see Fig. 8, to thedowel driving position II5 and serves to hold the dowel in this positiondirectly above the heel until the driving pin IIII is lowered and drivesthe dowel into the heel. When the slide I I4 is ,in its lowermostposition a dowel supplied by thetube I01 will dropin front of theforward end of this slide and will be yieldingly held in this positionby a spring I I6, the forward end of which extends through an opening inthe side wall of the casing to engage the dowel.

When the slide I I4 is advanced from its retracted position of Fig. 8 adowel entering the casing I08 will then drop upon the shoulder II! ofthe slide and will be held in this elevated position until the slide H4is again retracted under the action of the compression spring H8 whichyieldingly urges the slide to its retracted position against the stopH9. The means shown for periodically feeding the slide forward in itscasing I08 comprises the flexible cable I29 secured at I2I to the slideand which passes around a pulley I22 and upwardly to the sliding shaft88 of the drill press so that the upward movement of this shaft willtension the cable I20 and pull. the slide H4 forward. A spring I23ispreferably connected to this cable to hold the slide yieldingly at theforward end of its stroke.

The means shown for elevating the dowels in the hopper I05 to supply thetrough I III with these dowels comprises a vertically movable slide I24,the upper end of which is trough-shaped and slopes towards thetrough I Ito cause these dowels to slide from the upper end of the slide I24 intothe trough H0. Reciprocatory movement is imparted to the slide I24, inthe construction shown, by the rod I25, the lower end of which ispivotally secured to the outer end of the transversely extending leverI26, as best shown in Fig. 6. The other end of this lever is pivotallysecured at I21 to the supporting lugs I 20' and an intermediate portionof this lever rests upon the die operating lever 60. The arrangement issuch that each time the lever 60 is forced upwardly by its operating camit will raise the transversely extending lever I26 to thereby elevatethe dowel feeding slide I24.

Having described the various parts of the embodiment of the inventionshown, the operation is as follows: When it is desired to operate themachine the motor 43 is started and'the treadle 49 is held depressed toengage the clutch 45 and drive the clutch shaft 4|. This drives the timeshaft 35 through the chain 51 and rotates the cam 34 to periodicallyoperate the plunger 27 to cause the plunger to force a. heel H which hasbeen placed by hand in the position I of Fig. longitudinally of thegripping jaws I4 and I5 to the position II, and feeds the heel past thesaw I4.

While a heel is in the position II the drill 84 is lowered by the cam90, lever 9| and link 93 to bore a dowel receiving hole in this heel,and when the next heel is forced along the jaws I4 and I5 by the plunger21 it will engage the heel'that was last drilled and move it to theposition III to cause a dowel d to be driven in the hole in the heel.The dowels are supplied by the hopper I05 and are successively presentedto the heel by the device I08 in position to be driven by the heel bythe pin IOI. Means is also provided whereby when a heel is in theposition II the heel may be stamped by the dies 58. The cams 63 and 90are driven at the same speed as the cam 34 by the chain 98.

After a heel has been acted upon by the saw 14, drill 84}, stamping dies58, and has been strengthened by a dowel d driven in the heel by the pin"II, the heel is ejected at the discharge end of the jaws I4, I5.
